Maldanite Smithing

Overview

Right now only dwarves are capable of smithing Maldanite cores and metals. The iron dragons and Iron Court elves could smith maldanite, but magic is too deeply rooted in their smithing techniques for them to want to smith it. If they tried they would not be able to use magic to smith, as their magic would either be blocked or absorbed. Another factor in smithing maldanite is that the gas released by smithing maldanite can permanently cause mental damage to those who are not immune to it like the dwarves, iron court elves, and iron dragons. The gas can also cause permanent magical damage to those who smith it as well, which is another reason why Iron dragons, and iron court elves don't smith it.
Dwarves have no magic of their own, and the fact that they are immune to all the effects of maldanite cores, metal, and gas, makes them perfectly able to smith the metal. They have used maldanite cores to create weapons, airships, and more. If anyone else tries to use their technology they would either go insane or loose all their magical abilities.

Dwarven Maldanite Engineering

(Maldanite weapons, armor, tools, and tech, cannot be enchanted as they block and or absorb magic so an enchantment is utterly useless on them.)
Dwarven Martial weapons:
Without cores:
Dwarven weapons that just use the weapons are incredibly useful for combating magic users and are sold all over the world. Maldanite weapons keep their blades sharp for very long periods of time. Only needing to be sharpened three times a year at the very least. These weapons are also highly durable, it is very difficult to break them. But by far their most valuable aspect is that they can block a magic user from using their magic. Granted the weapon needs to maintain contact with their skin for this feature to work. But it is incredibly useful none the less.
With cores:
Maldanite weapons with cores can only be handled by dwarves, anyone else will have their magic absorbed or go insane or both. These weapons have a small radius in which they absorb magic, and once the blade makes contact with a magic user not only is their magic block, but it is absorbed, preventing them from using any magic for a long period of time.
Crossbows:
Dwarven crossbows are augmented with maldanite bolts and a maldanite cores. The bolt heads are made from maldanite so that when the get shot at into a magic user they will immediately stop them from using their magic. The bolts are designed so that if the shaft is pulled out the bolt head will dislodge and remain in the body. Built into the crossbow are maldanite cores, when the crossbow fires the core is struck with a mechanism that fires bolts at a faster and more deadly speed and strength. This makes even hand held crossbows deadly.
shields:
Maldanite shields aren't too different from steel or iron shields, other than being more durable and long lasting. while you can touch a magic user with the shield to prevent them from using magic, using the shield to do so isn't super affective. A maldanite shield wont protect you from magic, it can only block magic as long as its touching the magic user. So if fire is coming your way a maldanaite shield will have the same affect on it as a normal steel or iron shield.
However a shield with a maldanite core does have a useful affect. Within a 10ft radios any magic user cannot use their magic, and any magical energy sent to the shield will be absorbed. Depending upon the power of the magical attack it will either be absorbed entirely or greatly weaken the attack.
Armor:
Maldanite armor is not very different to iron or steel armor, other than being stronger and more durable. They also don't place the cores within the armor as its just easier to use other maldanite core contraptions rather than baking it into the armor.
Dwarven Airships:
Dwarven airships use large maldanite cores to lift the airships off the ground. They have large air sacks around the cores as well, these trap the maldanite gas that is constantly being fed to the cores to keep the ship aloft. There are large forges that smelt maldanite metal and produce the gas that is trapped within the sacks. The maldanite cores absorb the gas to stay powered. However once the gas stopps flowing the ship slowly looses altitude.
